The antenne of this genus are also clavate; but then they are 
ten-jointed, as in Bolitotherus. The specimen described below is one 
of Mr. Bates’s discoveries on the Amazons. 
Ozolais scruposa. (Pl. XVIII. fig. 1.) 
O. fusca, pube grisea induta. 
Hab. Ega. 
Dark brown, with a loose greyish pile; head with two rows of tuber- 
cles in front; prothorax very convex or gibbous above, with nine or ten 
crenatures on each side, the penultimate by far the largest and directed 
backwards, the base rather strongly emarginate for the reception of part 
of the scutellum; elytra seriate-punctate, with several large tubercles 
mixed with others smaller and more spinous; body beneath dark brown, 
closely punctured ; legs and antennze reddish brown, with scattered grey 
hairs. Length 2 lines. 
Inyxervs [ Bolitophaginee }. 
Caput ante oculos dilatatum; clypeus distinctus. Oculi magni, semi- 
divisi. Palpi mazillares robusti, apice oblique truncati, Palpi labiales 
art. ult. ovali, acuto. Zabiwm parum emarginatum. Mentwm trans- 
versum, antice sinuatum, postice constrictum. Antenne 11-articulate, 
clavate ; scapo elongato, crasso; art. 2 brevi; 3 obconico ; 4-8 breviter 
trigonatis; tribus ultimis clavam validam compressam formantibus (9 
valde transverso, 10 et 11 arcte applicatis, rotundatis). Prothoraz postice 
constrictus, angulis anticis productis; marginibus crenatis, haud foliaceis. 
Elytra elongata, parallela, prothorace haud latiora. Pedes mediocres ; 
tibie subcylindrice, inermes; tars? lineares, art. ult. ceteris simul sumptis 
vix breviore. Prosternum productum.  Mesosternum subvyerticale. 
Metasternum modice elongatum. Corpus parallelum, angustatum, 
tuberculatum. 
The narrow parallel form of this genus would at once distinguish 
it from any other in its subfamily ; and no other has yet been pub- 
lished with clavate antenne. I owe my specimen to Mr. Bakewell’s 
liberality. 
Tlyxerus asper. (Pl. XVIII. fig. 3.) 
I, griseo-fuscus, supra tuberculatus et punctatus. 
Hab. New South Wales. 
Brown, with a sparse greyish-ochreous pubescence; head with a 
large tubercle over each eye, and three smaller ones between them; 
prothorax with about eight crenatures on each side, the disk roughly 
tuberculate. Scutellum semicircular; elytra with six rows of tubercles 
on each, between each row two lines of well-marked punctures; body 
beneath dark brown, the legs and antenne reddish brown, all clothed 
with scattered greyish setulose hairs. Length 23 lines.
